On August 12, 1990, in the badlands of South Dakota, palaeontologist Peter Larson and his team from the Black Hills Institute unearthed the largest, most complete Tyrannosaurus Rex ever found. Dinosaur 13 chronicles an unprecedented saga in American history and details the fierce battle to possess a 65-million-year-old treasure. With consummate skill, filmmaker Todd Miller excavates layer after layer, exposing human emotion in a dramatic tale that is as complex as it is fascinating.
